UC San Diego engineers have developed a low cost, low power technology to help robots accurately map their way indoors, even in poor lighting and without recognizable landmarks or features. The technology uses WiFi signals, instead of light, to help the robot "see" where it’s going.
A high-fat diet after 16 weeks induced hypertension in rats, according to researchers from Henry Ford Health and Wayne State University in Detroit.
For most sea turtles, the journey to find the ocean from their nests is pretty straightforward. However, leatherback hatchlings more often crawl around in circles trying to find the ocean. Circling delays their entry into the ocean, wastes energy, and places them at greater danger from natural predators. Under different moon phases: bright light during full moon and only starlight under new moon, researchers have a better understanding of why this circling behavior happens and why it is most commonly observed in leatherbacks.
A new robot is capable of switching from an underwater drone to an aerial vehicle in less than one second. The robot also features a suction disc inspired by the remora fish, which enables it to hitchhike on wet or dry moving objects to significantly reduce its power consumption. It is designed for biological and environmental monitoring in marine ecosystems such as surveying ocean pollution in the open sea as the scientist of Beihang University, Imperial College London and Empa point out in a new study published in Science Robotics.

New research examines how cavefish developed unique metabolic adaptations to survive in nutrient-scarce environments. The study created a genome-wide map of liver tissue for two independent colonies of cavefish along with river fish to understand how cavefish metabolism evolved and how this may be applicable for humans.
A team of FSU researchers investigated the formation and spread of brown spots on bananas, a striking case of biological pattern formation. In research published in Physical Biology, the team described how the spots appear during a two-day window, rapidly expand, but then mysteriously stall, leaving a sharp distinction between spots of brown and the still-yellow peel.

A tropical spider species uses a “film” of air to hide underwater from predators for as long as 30 minutes, according to faculty at Binghamton University, State University of New York.
Researchers have identified distinct differences among the cells comprising a tissue in the retina that is vital to human visual perception. The scientists from the National Eye Institute (NEI) discovered five subpopulations of retinal pigment epithelium (RPE)—a layer of tissue that nourishes and supports the retina’s light-sensing photoreceptors. Using artificial intelligence, the researchers analyzed images of RPE at single-cell resolution to create a reference map that locates each subpopulation within the eye.

When it comes to fixing carbon, plants have nothing on soil bacteria that can do it 20 times faster. The secret is an enzyme that “juggles” reaction ingredients. Scientists hope to optimize this process for producing fuels, antibiotics and other products from CO2.
It’s been 50 years since the Tuskegee Study was disclosed to the American public. In May, a new riveting account of the Study, when government doctors intentionally withheld effective therapy for syphilis for 40 years in 400 African American men, will be published in the American Journal of Respiratory and Critical Care Medicine. The article explains the deeper everlasting lessons of the study.

Research by experts at the Universities of Birmingham and Bristol, published today in Royal Society Interface, shows cardiac surgery causes major dynamic changes in concentration of ACTH and cortisol, as well as their pattern of secretion. Using novel mathematical techniques, researchers developed a model of HPA axis activity that predicts the physiological mechanisms responsible for different patterns of cortisol secretion.
In an article published today in Scientific Reports (https://www.nature.com/articles/s41598-022-10466-8), researchers from Bar-Ilan University in Israel reveal that the brain learns completely differently than has been assumed since the 20th century. The new experimental observations suggest that learning is mainly performed in neuronal dendritic trees, where the trunk and branches of the tree modify their strength, as opposed to modifying solely the strength of the synapses (dendritic leaves), as was previously thought. These observations also indicate that the neuron is actually a much more complex, dynamic and computational element than a binary element that can fire or not. Just one single neuron can realize deep learning algorithms, which previously required an artificial complex network consisting of thousands of connected neurons and synapses. The new demonstration of efficient learning on dendritic trees calls for new approaches in brain research, as well as for the generation

Between the challenges of everyday life and more than two years of the COVID-19 pandemic, kids face more pressure and distraction than ever before, a combination of factors that has led to a mental health crisis among children in the United States. That crisis means that, more than ever, caregivers need to be equipped to talk daily to their children about thoughts, feelings and emotions, which in turn can help caregivers better support children if they have a mental health concern.

Oak Ridge National Laboratory, the largest Department of Energy science and energy laboratory in the country, is deeply invested in the big science capabilities and expertise needed to address the climate challenge on multiple fronts.
Anterior cervical discectomy and fusion is widely used to treat spinal disorders. The fusion involves placing a bone graft or “cage” and/or implants where the surgically removed damaged disc was originally located to stabilize and strengthen the area. The risk factors for cage migration are multifactorial and include patient, radiological characteristics, surgical techniques and postoperative factors. A study is the first to evaluate the effect of the range of motion, cage migration and penetration using variable angle screws and cervical spine models. The plate developed and tested by the researchers provided directional stability and excellent fusion, showing promising clinical outcomes for patients with degenerative cervical spine disease.

In Physics of Fluids, researchers from MIT characterized the flow and fracture of Oreos, finding the creme, which is officially "mushy" in rheological texture, tends to stick to one side of the cookie. They placed Oreos in a rheometer, a laboratory instrument they used to measured torque, and after the filling failed and the cookie broke apart, they quantified the amount of creme on each wafer by visual inspection. The authors investigated the influence of milk, cookie flavor, amount of filling, and rotation rate on the final creme distribution.
